Microwave-assisted, facile, rapid and solvent-free one pot two-component synthesis of some special acylals
A facile, rapid and solvent-free method for the conversion of acids and dihalomethane to the corresponding methylene diesters (acylals) using microwave as activators or assistor, is reported. This method is particularly powerful for the diesterification o
Solvent-free synthesis of symmetric methylene diestersviadirect reaction of aromatic carboxylates with 1,n-dihaloalkanes
An efficient methodology for the synthesis of symmetrical methylene diesters was developed through direct reaction of various aromatic carboxylates with 1,n-dihaloalkanes under solvent-free conditions. This strategy offers a high product yield, facile work-up and purification, and an environmentally friendly approach to obtain long-chain methylene carboxylate scaffolds with increased diversity.

Synthesis of esters from aldehydes or carboxylic acids with dichloromethane, dichloroethane or dichloropropane under mild conditions
Dichloromethane (DCM) as a C1 source has been discovered: methylene diesters from DCM and carboxylic acids or aldehydes with TBHP in water were efficiently synthesized. The reactions proceed under mild conditions and afford both aliphatic and aromatic met

DBU-CH3I, a potential substitute for CH2N2 in the preparation of methyl esters and methyl aryl ethers: Studies with assorted acids
DBU-CH3I has been poised to be a substitute for diazomethane in the preparation of methyl esters from carboxylic acids. The reactions can be carried out in commercial untreated acetone and acetonitrile, which have been exemplified with several methyl esters, otherwise it is difficult to prepare. Bis-esterification using diiodomethane can also be achieved in a similar fashion. Sufficiently acidic phenols are also conveniently O-methylated by the method. Copyright Taylor & Francis Group, LLC.

Efficient method for synthesis of methylene diesters using polyethylene glycol as a phase transfer catalyst
Methylene diesters were synthesized in high yields at room temperature by reacting the potassium salt of a carboxylic acid with dibromo methane under the conditions of solid-liquid phase transfer catalysis using poly (ethylene glycol)-600 (PEG-600) as the
